Perez dubbed his model a "#diva" -- in the best sense of the word -- when he shared a picture of them on the red carpet at the show.

"I wanted something colorful and dramatic," Perez told People. "I showed her some sketches and she selected one. Before I was a costume designer, I ran costume workrooms for movies, so designing and making clothes is second nature to me."

The fashion-forward "The Office" writer and alum was on hand Saturday to present an award with costar and "Mindy Project" co-writer Ike Barinholtz at the 16th annual show at the Beverly Hilton Hotel in Beverly Hills. Perez, who was not nominated that evening, has designed the colorful and high-end ensembles of Kaling alter-ego Dr. Mindy Lahiri on the Fox comedy since 2012.

"Salvador had a vision and I was just excited to be part of it — I trust him implicitly," Kaling told the magazine. "The color, the silhouette, the train, it's all decadence and drama, cut in the most flattering shape. It felt like I was getting married, so much attention was paid to me looking my absolute best. When you have a gown custom-fit to you, there's not the hell of trying on dresses and your ego getting hurt because it doesn't fit in certain places."

"I loved your Sal Perez dress last night - congrats to you both for killing it," Banks tweeted at the pair.

"thanks Liz!" Kaling replied, "I can't wait to see @MrSalPerez's new Bella looks for the sequel!!!"

The night's big winners included Patricia Norris for "12 Years a Slave," Suzy Benzinger for "Blue Jasmine" and Trish Summerville for "The Hunger Games: Catching Fire" in film, according to All the Rage. In television, awards went to Ellen Mirojnick for "Behind the Candelabra," Caroline McCall for "Downton Abbey" and Tom Broecker for "House of Cards."
